Process for producing ornament glass

Abstract

The invention relates to an ornamental glass producing process, mainly comprising the steps of: 1.1) bathing SiO2 50-72 weight shares, Na2O 12-17 weight shares, B2O3 1-3 weight shares, ZnO 0.1-2 weight shares, BaO 1-10 wegiht shares, PbO 1-6 weight shares, K2O 2-15 weight shares and recovered waste glass 30-35 weight shares; 1.2) uniformly mixing them, using coal tar as fuel to heat the melting furnace, controlling the temperature at 1500-1560 deg.C, and melting them into glass solution; 1.3) making the glass solution flow through a discharging tank beside the melting furnace, controlling the discharging tank at 1200 deg.C, making the solution from the bottom discharging outlet linearly flow via buffer device into the crack of a mould, roll-forming stripe blanks, then breaking stripes and trimmings, shaping and graded-screening, and finally forming the semi-finished products of ornamental glass. And it has beneficial effects of: combinationally optimizing mature techniques in the original process, reducing labor strength of personnel, raising producing efficiency and stabilizing product quality.

Description

technical field [0001] The invention relates to the field of glass production technology, and mainly relates to a production technology of decorative glass. Background technique [0002] At present, the production of decoration or clothing glass is due to the small size of the product, many mold specifications, frequent replacement, short life span, and small scale. It is heated and melted in a small kiln. Then the glass solution is pressed through a mold to form a rough blank for decoration or decoration processing. [0003] The schematic diagram of the production process of the traditional process is shown in Figure 1: its existing disadvantages: 1. One cylinder (crucible) is fired once, because it is intermittent production, one furnace per 24 hours, which consumes energy and has low output, 9 cylinders a day The output is only 1.2 tons of blanks (10# specification hot-drilled glass). 2. Feeding and stirring are all manual operations, with high labor intensity and many...

[0003] The schematic diagram of the production process of the traditional technology is shown in Figure 1: its disadvantages: 1. One cylinder (crucible) is fired once, because it is intermittent production, one furnace per 24 hours, which consumes energy and has low output, 9 cylinders a day The output is only 1.2 tons of blanks (10# specification hot-drilled glass)

2. Feeding and stirring are all manual operations, with high labor intensity and many human influence factors, resulting in serious waste of raw materials, unstable product quality and high production costs
